To all whom it may concern.'

Be it known that EDWARD L. AIKEN, a`

' citizen of the United States, "and a resident a granted to me onSeptember 3, 1912.

Myinvention relates to apparatus for the 'projection of moving pictures.In 4apparatus of this character, as is pointed out in Patent No.967,293, granted to me on August 16, 1910, it is important that the ilmupon whichy the pictures arecarried shall not be exposed to the heatemanating from the projecting light for more than a very brief intervalof time, because such films are ordinarily composed of Celluloid or likeinfiammable material andthe heat referred to is ator fails to properlyiiicient to ignite such a film very quickly. Ordinarily, since the film`travels rapidly past exposure position it Vdoes not become heated to adangerous extent, but in case the mechanism becomes deranged so as notto properly feed the film, or in case the oper ope-rate the saidmechanism, that part of the iilin in front of the exposure opening maybecome ignited and the fire spread to the remainderl of the iilm and toother inflammable materials with disastrous results.

The principal object of the present invention is the provision of aimproved'receptacle for holding the supply and. take-up reels on whichthe .body of the film' is containedl; so that if the portion of thefilmy situated between said receptacles becomes ignited, the flame willbe effectively smothered before reaching the body of the film, wherebythe danger of conlagration is minimized. Although in the apparatusherein illustrated there is very little danger of the film becomingignited owing to theuse of automatic means for shutting off the lightfrom the film when the same is not being moved with suticient rapidity,which means is specifically described and claimed inthe applicationabove referred to, it isto be understood, of course, that this inventionis Specification of Letters Eatent.

Patenten nay e, isis.

Divided and this application filed July 525,

Serial No. 136,812.

applicable to apparatus not provided with such means, and in which thisdanger is very considerable. i

l/Vth the above and related objects in' View, my invention consists inthe combinations of elements and construction of parts hereinafter morespecifically described and claimed.

In order that my invention may be more clearly understood, attention isdirected to the accompanying drawings forming a part of thisspecification, in which the same ref- `closed position,

erence characters are used, to designate corresponding parts throughoutand in which Figure 41 is a side elevation of a complete apparatusconstructed in accordance with my invention;

Fig. 2 is a detail view of one of the reel receptacles or boxes, thecover thereof being open;

Fig. 3 is a section on line 3 3 of Fig. 2;

Fig. 4 is a detail plan view of the hinged plate shown in Fig. 2;

Fig. 5 is a section on line 5 5 of Fig. 2;

Fig. 6 is a section on line 6-,6 of Fig. 4 and Fig. 7 is a view of thespring by which the hinged plate ofFig. 4 is held in its closed oroperative position.

The traveling film 1 is contained upon a supply reel 2 which turnsfreely upon a pin 3 rigid with the box or. receptacle 4. rlhis box isprovided with a hinged cover 5 which carries a spring 6 for pressingupon and retarding the reel y2 when. the cover 1s in its a latch 7 beingprovided for holding the cover in said position; The box 4 is rigid witha standard 8 which issecured n A' to a vertical main support 9 by whichthe frame 10 of the apparatus for manipulating the film is alsosupported. rEhe bottom wall 11 of tlielbox 4 is cut away as shown inlFig.

6 and the cut away portion isA covered .by a

plate 12 riveted to the bottom 11. This plate is provided with anaperture 11,3 in which is situated a pair of rollers 14` vand 15, thesamebeing journaled in lugs 16 depending from and integral with theplate 12.' The intermediate portion of the roller 14 is Jcut awayforming collars17, 17 at the ends `thereof. Thespaoe between the innerperipheries of the collarsl? andthe roller ioo j is just sufficient topermitthef'passage of the ilm therebetween, and 's the lm is udrawn downbythe feed mechanisnnfthe intermediate its edges, that is, the part uponrollers turn freely on their pintles to'allow the film to pass withoutfriction. The margins of the film bear against the collars 17 of theroller 14, whereby th part of the film which the pictures areprinted,.will be `protected against any -inj-ury. Abovethe plate 12v ishinged a platelS whose pivot pin 19 is journaled in a bearing 20integral 'with the plate 12. rlhe plate 18 during the op- 'eration` ofthe projecting apparatus occupies the position shown in Fig. 6, beinglocked in such position by the spring latch l 21. This latch consists ofa plate .of spring metal riveted 'at its upper end to the box 4 andcarrying at its lower end a locking pin 22 which is adapted to engagethe forward end of the ears 23 carried by the plate 18.

vlObviously, 'a slight pressure upon the latch 21 toward the wall of thebox 4 will release the plate 1 8 and allow it to be turned on its pivotas indicated in dotted lines in Fig. 2, whereby the film 1 may be easilythreaded.

-between the rollers 14 and 15. Between the ears 23,' 23 and journaledtherein is a roller 24 around which the film v1 is adapted to pass inits path from the reel 2 to the rollers 14 and 15.` When the plate'18 isin its normal position as in Fig. 6, a long narrow passage 25.is formedbetween the platesf18 and 12, the sides of which are closed by thedepending anges 26 of the platev 18 which overlap the vertical flanges27 of the plate (See Fig. 3). This restricted passage contains verylittle air, not enough to Asupport combustion of the film.1 and as Ihave ascertained -by experiment, the flame of@ burning. film' islinvariably smothered after i traveling a very short distance into thesaid lusual cranka as indicated in dotted lines,

Fig. 1, said gears and sprockets being all mounted in the frame 10. TheattachmentV for automatically cutting off the light wheno the film 1sstationary, which forms the subject matter of thev application SerialNo.

286,424 referred tol above, is carried by a y frame '108 attached to theframe 10.
